I'll be honest I bought one of these and never again.
You don't need to add oil for things like sausages, chicken pieces and ready oven chips/frozen chips.
It doesn't drain any oil off though so you will find your food swimming in oil in the bottom, if its things like sausages or chicken you cook. Also the paddle gets stuck as food gets jammed between it and the wall of the fryer. The paddle itself is a pain in the ass to clean, food gets stuck in the wee crevices on the underside of it.
Also I had mines for a grand total of 4 months when the lid cracked. Tefal said because I still didnt have my receipt then I couldn't get a replacement. I sent them my credit card bill instead but they said it wasnt good enough.
So I bought a new lid for £25 from teh spares site.
Then the paddle stopped turning. This is an un-replaceable part fault. I needed a new actifry, but you guessed it, no replacement from Tefal.
Apparently the newer ones are more reliable but honestly I wouldn't buy one again. Great when they work, soul crushing to spend £200 on a fancy chip pan that keeps breaking.
It lasted a grand total of 8 months and its not like we used it every single day, as I was on CD for a while.
